tiriglnal application filed July a1, 1919, Serial Ito. 312,190. Divided 1920. aerial lilo. 373,113.

To all whom it may concern: Be it known that I, Wrnmun JEAN, a citizen of the United States, residing at Lowell,

metal valve in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements 'in Valves; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others sk1lled in the art to,

which it appertains to make and use the same.

My invention has for its object to provide an extremely simple and inexpensive, yet an eficient, reliable and easily operated valve which may well be used on the heating systems of automobiles for directing the exhaust gases from the'engine either to the usual exhaust pipe and mufier, or to branch piping leading to a heater.

With this object in-view, the inventlon resides in the novel construction hereinatter described and claimed, the descriptive matter being supplemented by the accompanying-Pdrawi gs.

igure 1 is a top plan view of a valve constructed in accordance with my invention.

Fig. 2 is a side elevation.

Figs. 3 and 4 are respectively vertical and horizontal sections on the planes indicated by the lines 33 and H.

The present application is divisional of my pending U. S. application, Serial No. 312190, filed July 21, 1919, which application is devoted to a heating system in which the subject matter of the present case is embodied.

In the, drawings accompanying this description the numeral 24 designates a cast casing having a circular plug socket 25 whose upper end is closed bye-a removable plate 26 carrying a stufling x 27 and a pair of vertical posts 28 upon which a segmental rack 29 is mounted, the three parts 26, 28 and'29 being preferably cast of a single piece and secured to the casing 24 by screws 30.

The casing 24 is provided with two ogposed nipples 31 flanged at 32 for attac Inent to the exhaust manifold, a portion of which is indicated at 3, and such casing is equipped also with a third flanged nipple 33 to which a two-way coupling 34 is attached. Pipes 5 and 5"- lea from the two openings in the OOHPllIifi 3% to the heaters Specification of Letters 'Eatent.

and. this application filed April 23,

when two of the latter are used, but when only one heater is employed, but one open- 112% of the coupling 34 is necessary, and the 0 or may be closed by an appropriate plug not shown. a

A cylindrical valve plug 35 isreceived rotatably in the plug socket 25 and is provided with a transverse passage 36. This passage permits all of the exhaust gases to pass through the manifold 3, allows all of said gases to. travel through the heater orheaters, or permits a division of the gases so that they pass partly into the heaters and partly through the manifold. Stops 37 on the upper endof the plug 35, and another stop 38 on the lower side of the cover plate 26, serve to limit the turning movement of the plug 35, and l provide means on the stem 39 for holding it in any position to which it may be set. This holding means by preference consists of a crank-arm 40 the stem 39 and a spring pressed pin 41 mounted on said arm and engaging with the rack 29. Anysuitable handle may be employed for turning the stem 39 to set the valve in the desired'position.

By the use of the device, the exhaust gases may be so accurately controlled, that the heater or heaters are made to raise the tempei'ature of the automobile to practically any desired degree. 7 i he simple and inexpensive construction of the device renders it advantageous to manufacture and market, yet such device is highly eficient and durable and desirable in every way. Since probably the best results may be obtained from the details'disclosed, such details may well be'followed, but within the scope of the invention as claimed, numerous minor changes may well be made. I claim: 7 g I A valve of the class described comprising a substantially cylindrical vertical casing having a plug valve socket in its upper side, an inlet into said socket, and an outlet from said socket, a valve plug having a passa for controlling communication between said inlet and said outlet, a removable cover plate for said lug socket secured to the upper side of said casing, a stem rising from said plug to a point above said cover plate,

a pair of posts rising from said cover plate at points spaced outwardly from said stem, an arcuate segment supported horizontally by said posts in concentric relation with said are rot stem, the upper side of said segment heing the upper end of said pin having a knob provided with spaced teeth, a handle exadapted to be raised to release the p111 and tending laterally from said stem over said to then serve as means to swing said handle 10 1 se ent and a spring-depressed pin slidto operate the valve stem.

5 ah carried by the outer end of said handle In testimony whereof -I'ha ve hereunto set an engaging the teeth of said segment to my hand. hold the stem and plug in adjusted positiony I WILFRID JEAN.
